  • the separating and distributing device of the present invention is comprised of two identical elements effect tothe element; I0, .Referringnow to FigureV 2 it ⁇ is.
  • theelernent Ll eomprissa hub view showing elevation and I3 and a plurality of teeth I4 which are circumferentially spaced and extend upwardly from the hub I2 in a direction generally normal to the plane of the hub.
  • the hub there are provided four protuberances I5, I6, Il and I8 which lie in generally parallel relationship to the teeth I4 and generally normal to the plane of the hub.
  • the teeth 2U of the element I In between the teeth I4 there depend the teeth 2U of the element I.
  • the separating and distributing device is constructed by placing two identical elements I and I I in mutually inverted position with the respective teeth interdigitating.
  • each tooth I4 and 2B are in the form of an isosceles trapezium so that when these teeth are interdigitated slits 2l are deiined which also have the shape of isosceles trapezia with the narrow side of the slit facing outwardly of the separating and distributing device.
  • Toward the inside the top flat of the teeth is bevelled with the same slope as that of the sides of the teeth as a result of which after interdigitation a slit 22 is formed which is also generally triangular in shape as can be seen.
  • the protuberances I5, I6, I'I and I8 are each provided with a central cavity at 23, 24, 25 and 26 respectively. Similar cavities are provided in the protuberances of the element I0, only one of which shows in Figure 1 at 21.
  • a guiding pin such as is shown at 23 in Figure 1 is inserted in each of the cavities 23, 24, 25 and 26 and projections above that cavity can be received in the cavities of the protrusions from element I0.
  • the height of the protrusions of the elements IU and II controls the width of the opening between the teeth.
  • protrusions are arranged within the annulus defined by the teeth and the two elements ID and II are fully identical it is necessary that the ratio of the number of teeth to the number of protrusions be a whole number. It is also necessary that the protrusions be arranged symmetrically with respect to each other and that the angle alpha (see Figure 2) between the radius through the center of the outer surface of the tooth lying nearest the protrusions be onequarter of the angle between the radii to said centers of two successive teeth of an element.
  • the angle alpha see Figure 2
  • a slit By choosing a suitable shape for the cross section of the teeth a slit can be obtained which discharges or has its larger dimension toward the inside of the device.
  • the cross section can have a shape of a trapezium as previously described or may be a half moon or a triangle. Besides a straight shape the sides of the teeth can also have any other shape so long as this does not give rise to difliculties during the molding and pressing of the elements. In practice it has been found desirable so to construct the teeth that the slits at their entrance and/or exit. are bounded by parallel lines such as are indicated at y--y in Figure 1.
  • a very narrow slit can -be achieved and yet this slit can be easily cleaned when the elements are dismantled so that the spaces between the teeth are very substantial.
  • the possibility for range of adjustment of the slit opening is determined by the slope of the sides of the teeth.
  • the width of the slit can be determined by the height of the protuberances and this may be fully predetermined during manufacture. It is possible, however, to change a. ready cast element at will by grinding ofi the teeth as well as the protrusions and this was not possible in constructions prior to the present invention.
  • protrusions are also possible to use instead of protrusions as uninterrupted collar having apertures therein.
  • protuberances would be lfrom the interior to the exterior of the device,
  • the element is sprayed in many directions.
  • Figure 5 the champferings 35 at the sides of the spaces between the teeth have been arranged in such a way that with the bevelled inner surfaces 36 of the teeth 33 a slit is obtained which runs A almost vertical.
  • the angle of the flat 36 with the horizontal and that of the fiat 35 with respect to the horizontal must be equal again with the angle of the sides of the teeth with the horizontal.
  • the teeth have a curved outer surface or at least are bent at their upper and lower extremities.
  • FIGs 3 and 4 illustrate two alternative constructions for the connection of two elements together.
  • a hollow glass screw bolt 3'! is shown which can be used to fasten the device to the bottom of a filter 45 by operation of its threaded shank.
  • the screw -bolt is provided with four ports 31a leading radially to the interior of the device and with a head 4i which, through a gasket 42, bears against the top of the device.
  • the upper element of the device bears reference numeral 43 in Figure 3, while the lower element thereof bears reference numeral 114.
  • the teeth and slits correspond to the disclosure heretofore made and the protuberances as illustrated include one at 45 having a central socket and one at 45 having a projecting portion engaging the socket.
  • FIG 4 a hollow collar bolt is shown for attaching the device to a filter bottom or the like.
  • the filter bottom is indicated at 41
  • the hollow collar bolt is represented by the numeral 48
  • the device is generally indicated at 49.
  • the upper surface of the collar bolt is externally threaded for coaction with an internally threaded cap 50 which in threaded engagement with the collar bolt compresses a washer 5l 'to bear down on top of the device 39.
  • the collar bolt has a flange at 52 which engages the inner surface of the filter bottom.
  • the collar bolt is provided with radial slits 48a similar in structure and function to the slits 31a of Figure 3.
  • FIG 6 there is shown a device 53 according to the invention provided with a screw bolt 54 similar in structure and function to the bolt 4l of Figure 3.
  • the filter bottom is represented at 55 and the liquid discharging from the filter flows in the direction of thev arrow into the hollow screw bolt and radially out through the slits of the device 5l.
  • Figure '7 there is shown a construction involving three serially arranged devices 56, 5l and 58 which are held by a collar bolt 59 and a cap 68 in stacked relationship with respect to a filter bottom 6 I.
  • the operation is similar to that previously described.
  • Figure 8 eight units are shown mounted on a tube 62 which passes through the Wall 63 of a Water purification plant.
  • the number of units on any tube can be increased or decreased at will and several such sets can be mounted near the bottom of a purification plant.
  • the water purification device according to the present invention is manufactured from glass.
  • the device can be made, from any material suitable to the liquid or gas which it is going to handle.
  • the device can be used for the drying of steam. In that case the steam to be dried is led from the exterior to the interior of the device and water drops present in the steam are retained by the slit.
  • a separating device for use with filters or the like comprising a pair of identical elements; each having a central hub portion defining a, central passageway, a plurality of teeth integral with the hub portion and arranged in circumferentially spaced relation extending in a common direction generally normal to the hub portion, and a plurality of integral protuberances extending from the hub within the space defined by the teeth; said elements being arranged in mutually Vinverted relation with their teeth interdigitating and said protuberances interlocking to control the axial and circumferential spacing between the interdigitating teeth.
  • a separating device for use with filters or the like comprising a pair of identical elements each having a central hub portion defining a central passageway, a plurality of teeth arranged in circumferentially spaced relation extending ina common direction generally normal to the hub portion and a plurality of protuberances extending from the hub within the space defined by the teeth; said elements being arranged in mutually inverted relation with their teeth interdigitating and said protuberances interlocking to control the spacing between the interdigitating teeth, said protuberances being arranged symmetrically with Y ment with the outer surface of the next adjacent tooth.
